tests/swscale: disable fate-sws-ops-list on BE platforms

Browse Source 
The issue is that every le/be pair ends up with a swapped op list:

 rgb24 -> rgb48be:
   [ u8 XXXX -> +++X] SWS_OP_READ         : 3 elem(s) packed >> 0
   [ u8 ...X -> +++X] SWS_OP_CONVERT      : u8 -> u16 (expand)
-  [u16 ...X -> zzzX] SWS_OP_SWAP_BYTES
-  [u16 ...X -> zzzX] SWS_OP_WRITE        : 3 elem(s) packed >> 0
+  [u16 ...X -> +++X] SWS_OP_WRITE        : 3 elem(s) packed >> 0
     (X = unused, z = byteswapped, + = exact, 0 = zero)
 rgb24 -> rgb48le:
   [ u8 XXXX -> +++X] SWS_OP_READ         : 3 elem(s) packed >> 0
   [ u8 ...X -> +++X] SWS_OP_CONVERT      : u8 -> u16 (expand)
-  [u16 ...X -> +++X] SWS_OP_WRITE        : 3 elem(s) packed >> 0
+  [u16 ...X -> zzzX] SWS_OP_SWAP_BYTES
+  [u16 ...X -> zzzX] SWS_OP_WRITE        : 3 elem(s) packed >> 0
     (X = unused, z = byteswapped, + = exact, 0 = zero)

I'm not sure of a good work-around that's not needlessly difficult to
implement, so just disable it on BE platforms for now. The actual underlying
conversions should still be covered by the sws-unscaled test.
